Privacy

Cordless telephones are radio devices. Communicationsbetween the handset and base of the cordless telephone areaccomplished by means of radio waves which are broadcastover the open airways. Because of the inherent physicalproperties of radio waves, communication can be received byradio receiving devices other than your own telephone unit,consequently, any communications using the cordlesstelephone may not be private.



SECTION 4 IMPORTANT ELECTRICAL CONSIDERATIONS

Warning!Do not attempt to unplug any appliance during an electricalstorm.

Unplug all electrical appliances when you know an electricalstorm is approaching. Lightning can pass through yourhousehold wiring and damage any device connected to it. Thistelephone is no exception.

Caution:Changes or modifications to this product not expresslyapproved by NEC America, Inc., or operation of this productin any way other than as detailed by this manual, could voidyour authority to operate this product.

Range

The new telephone is designed to achieve a maximum range ofup to 150 feet (depending upon the environment) bytransmitting and receiving according to the highestspecifications set forth by the FCC. We have rated this phoneto operate at a maximum distance with the qualification that therange depends upon the environment in which the telephone isused. Many factors limit range, and it would be impossible toinclude all of the variables in our rating. The maximum rangerating of this telephone is meant to be used as a means ofcomparison against other range claims.

Telephone Line Problems

The FCC has granted the telephone company the right todisconnect service in the event that your telephone causesproblems on the telephone line. Also, the telephone companymay make changes in facilities and services which can affectthe operation of your unit. However, your telephone companymust give adequate notice in writing prior to such actions toallow you time for making necessary arrangements to continueuninterrupted service.



If you are having trouble with your telephone service, youmust first disconnect your telephone to determine if it is thecause of your problem. If you determine that it is the cause,you must leave it disconnected until the trouble has beencorrected.

Radio Interference

Radio interference may occasionally cause buzzing andhumming in your cordless handset, or clicking noises in thebase unit. This interference is caused by external sourcessuch as TV, fluorescent lighting, or electrical storm. Your unitis NOT DEFECTIVE. If these noises continue and are toodistracting, check around your office to see what appliancesmay be causing the problem. In addition, we recommend thatthe base not be plugged into a circuit that also powers a majorappliance because of the potential of interference. For bestperformance, ensure that the antenna on the base unit is fullyextended.

In the unlikely event that you consistently hear other voices ordistracting transmissions on your telephone, you may bereceiving radio signals for another cordless telephone or othersource of interference. If you cannot eliminate this type ofinterference, you need to change to a different channel.

Finally, it should be noted that some cordless telephonesoperate at frequencies that may cause interference to nearbyTVs and VCRs. To minimize or prevent such interference, thebase of the cordless telephone should not be placed near oron top of a TV or VCR. If interference is experienced, movingthe cordless telephone farther away from the TV or VCR willoften reduce or eliminate the interference.

More than One Cordless Telephone

If you want to use more than one cordless telephone in youroffice, they must operate on different channels. Press thechannel key to select a channel that provides the clearestcommunication.
